Python: Concatenate int and string

There are various ways to concatenate int and string.

 

Approach 1: Converting int to string

str() function is used to convert int to string.

 

Example

msg = 'My age is ';
age = 32

str1 = msg + str(age)

 

Approach 2: Using % operator.

str2 = "%s%s" % (msg, age)

 

Approach 3: Using format function.

str3 = "{}{}".format(msg, age)

 

Approach 4: Using f-strings.

str4 = f'{msg}{age}'

Find the below working application.

 

string_int_concate.py

msg = 'My age is ';
age = 32

str1 = msg + str(age)
print(str1)

str2 = "%s%s" % (msg, age)
print(str2)

str3 = "{}{}".format(msg, age)
print(str3)

str4 = f'{msg}{age}'
